If you want to game, PC is the better option, but as far as creating things, like photoshop and editing software, Mac is without a doubt the best choice. Whilst they're expensive, the things you get with them is top of the range kit. iMovie is to date one of my favourite editing softwares, it's easy to use and does almost everything I need it to. And if your mac doesn't come with it, it's only like £10, which isn't an extensive amount. I got a mac at the beginning of this year, and I would never go back to PC ever.
